Painting a brick fireplace sounds simple. Grab some paint, slap it on, done. But if you skip the prep work, you’ll end up with peeling paint, blotchy coverage, and a fireplace that looks worse than before. That’s the reality most guides won’t tell you upfront.
Here’s the good news: how to paint a brick fireplace is a project any homeowner can finish in a weekend. You don’t need professional experience. You need the right steps, the right products, and about $80–$150 in supplies. This guide gives you clear steps, real tips from job-site experience, and honest advice on when painting is a good idea and when it’s not. You’ll learn what tools to use, how to avoid common mistakes, and how to get a finish that lasts for years.
Key Takeaways
- Clean and prime before anything. Skipping this causes paint to peel within months.
- Use a masonry-specific primer. Regular primers won’t bond to porous brick.
- Budget $80–$150 for supplies. Professional help runs $300–$600.
- Paint only the outside of the firebox. Never paint inside where flames reach.
- Drying time and curing time are different. Wait 30 days before building a fire.
Should You Paint Your Brick Fireplace?
Before you open a single can of paint, ask yourself this honestly.
Painting is a good idea if:
- Your brick looks dated, dirty, or discolored
- You want to brighten a dark room
- You’re going for a modern or clean aesthetic
- The brick has minor staining that cleaning won’t fix
Painting is NOT a good idea if:
- Your brick is in poor condition with crumbling mortar
- You love the natural brick look and might regret losing it
- You’re planning to sell soon and buyers in your area prefer natural brick
The one thing most guides skip: Painted brick is very difficult to reverse. Removing paint from brick requires chemical strippers, sanding, and hours of hard work. It’s not impossible, but it’s painful. Go in knowing that.
If you’re committed, keep reading.
Important Technical Warning: Efflorescence
Before you start, look for a white, powdery substance on your bricks. This is called efflorescence. It is a salt deposit caused by moisture moving through the masonry. If you paint over this, the paint will bubble and flake off. You must scrub this away with a stiff brush and a neutralizing wash before applying any product.
Whitewash vs. Limewash vs. Paint: Which One Is Right?
This comparison alone puts this guide ahead of most. Here’s a quick breakdown:
Option | Look | Reversible? | Cost |
Paint | Solid, opaque color | Very difficult | $80–$150 |
Whitewash | Semi-transparent, rustic | Somewhat | $40–$80 |
Limewash | Textured, aged, organic | Easier than paint | $60–$120 |
Paint is the best choice if you want a clean, modern style that covers everything. If you want to see texture and character, you might want to think about whitewashing or limewashing. This guide is mostly about full paint, but it’s important to know what your alternatives are ahead of time.
Choosing the Right Paint Color and Sheen
Color:
White and gray are the most popular choices for a painted brick fireplace. They brighten a room and work with almost any decor style.
But don’t feel locked in. A deep navy, charcoal, or even terracotta can turn your fireplace into a true focal point. Pull a color from something already in the room, like a rug, sofa, or artwork.
Popular choices:
- Bright white for a clean, airy feel
- Warm greige for a cozy, neutral look
- Charcoal or black for a dramatic, modern statement
- Navy blue for a bold focal point
Sheen:
- Matte or flat: hides imperfections, keeps the natural brick texture visible. Best for rough or uneven brick.
- Eggshell: slight sheen, easy to wipe clean, most popular choice for fireplaces.
- Semi-gloss: reflects more light, easiest to clean, but shows every bump in the brick.
For most DIYers, eggshell is the sweet spot.
Real Cost Breakdown
Here’s what no competitor tells you clearly:
Item | Estimated Cost |
Wire brush | $5–$10 |
TSP cleaner or degreaser | $8–$15 |
Painter’s tape (wide) | $6–$10 |
Drop cloth | $8–$15 |
Masonry primer (1 qt–1 gal) | $18–$35 |
Interior latex paint (1 qt–1 gal) | $25–$55 |
Thick nap roller (½ inch) | $8–$12 |
Brushes (2–3 inch) | $6–$12 |
Total DIY | $84–$164 |
Professional service | $300–$600+ |
Doing it yourself saves real money. And the results, when done right, look just as good.
Supplies Checklist: Painting a Brick Fireplace

- Stiff wire brush
- Shop vacuum or vacuum with brush attachment
- TSP (trisodium phosphate) cleaner or a strong degreaser
- Bucket, sponge, and clean rags
- Wide painter’s tape (2–3 inch)
- Drop cloths
- Safety goggles, gloves, and a dust mask

How to Paint a Brick Fireplace: Step-by-Step Guide
Step 1: Brush Out Debris
Use a stiff wire brush to scrub the entire surface. Work the brush deep into the mortar lines. You’re removing loose debris, old soot flakes, and anything that would prevent paint from sticking.
After brushing, vacuum the entire surface. Don’t skip this. Loose dust under your primer causes bubbling later.
Check the mortar while you’re at it. If any sections are crumbling or cracked, repair them with a masonry repair caulk or mortar mix before moving forward.
Time needed: 30–45 minutes
Step 2: Deep Clean the Brick
This step is where most DIYers cut corners. Don’t.
Mix TSP (trisodium phosphate) with water according to the package directions. TSP cuts through decades of soot, grease, and mineral residue that soap and water alone won’t touch.
Apply the solution with a sponge and scrub in circular motions. Rinse with clean water and a fresh sponge.
Do a spot test first. Apply the cleaner to a small, less visible area. Some cleaners can cause discoloration on certain brick types.
If soot is heavy, a second round of cleaning may be needed.
Critical: Brick is porous and absorbs a lot of water. Let it dry for a full 24 hours before priming. Painting over damp brick is one of the top reasons paint peels early.
Time needed: 45–60 minutes + 24 hours drying
Step 3: Tape and Protect
Apply painter’s tape along the walls, floor, mantel, and any trim you don’t want painted. Lay drop cloths on the floor around the fireplace.
Take your time here. Clean tape lines make the finished project look professional.
Step 4: Apply Masonry Primer
This is the most important step in the entire process.
Regular wall primers will not bond properly to brick. You need a masonry primer or a high-adhesion primer like Zinsser Bullseye 1-2-3 or Sherwin-Williams Concrete & Masonry Primer.
Use a 2–3 inch brush to work primer into all the mortar lines first. Then use your ½ inch nap roller to cover the face of the bricks.
Because brick is so porous, expect to use more primer than you think. Two coats of primer are almost always necessary, especially if your brick has staining or if you’re going with a light paint color.
Let the first coat dry fully, then apply the second. Let the second coat dry overnight.
Time needed: 1–2 hours application + overnight drying
Step 5: Apply Your Paint
Start with the mortar lines using a brush. Then roll the face of the bricks using your ½ inch nap roller.
Work in small sections so you can catch any drips before they dry. Keep a wet brush nearby for touch-ups in the mortar lines.
Plan on two coats. One coat is rarely enough on porous brick. Let the first coat dry fully (at least 4 hours) before applying the second.
The second coat is what gives you that clean, consistent finish. Don’t rush it.
Time needed: 2–3 hours per coat + drying time between coats
Step 6: Paint the Mantel and Trim
Once the brick is done, step back and look at the mantel.
A few options:
- Paint it the same color as the brick for a sleek, monochromatic look
- Go with crisp white for contrast against a darker brick color
- Use a semi-gloss finish on the mantel since it gets touched more and needs to be wiped down
If your mantel has built-in shelves or connects to baseboards, painting them the same color creates a clean, pulled-together look.
Common Mistakes to Avoid
- Mistake 1: Not letting the brick dry after cleaning the wet brick under the primer leads to peeling. Wait the full 24 hours.
- Mistake 2: Using regular wall primer It won’t bond to masonry. Always use a masonry-specific primer.
- Mistake 3: Skipping the second coat of primer One coat won’t seal soot stains. They’ll bleed through your paint color within weeks.
- Mistake 4: Painting inside the firebox Standard interior paint is not heat-resistant. It will burn and release toxic fumes. If you want to paint inside the firebox, use a heat-resistant or heat-proof fireplace paint rated for high temperatures. Rust-Oleum High Heat paint is a solid option.
- Mistake 5: Confusing drying time with curing time Paint may feel dry to the touch in a few hours. But full curing takes 30 days. Don’t build a fire until the paint has fully cured.
Tips for a Better Finish
- Wrap wet brushes tightly in plastic wrap and refrigerate between coats. They’ll stay workable and save cleanup time.
- Use a roller extension pole for tall fireplaces. It gives you better control and saves your back.
- If your brick is very rough or textured, use a ½ inch nap roller. For smoother brick, a ⅜ inch nap works fine.
- Work in a well-ventilated space. Open windows and use a fan to move air through the room.
- Bring in a space heater in cold months to help the paint cure faster.
When to Call a Professional
DIY works well for most standard brick fireplaces. But there are times when professional help makes more sense.
Consider hiring out if:
- Your mortar needs significant repair before painting
- The fireplace is floor-to-ceiling and hard to access safely
- You want a flawless finish without the learning curve
- You’re dealing with heavy efflorescence or mineral buildup that won’t clean off

Frequently Asked Questions about Painting a Brick Fireplace
Can you paint a brick fireplace?
Yes. Any brick fireplace can be painted as long as the brick is structurally sound and properly cleaned and primed first.
What is the best paint for a brick fireplace?
Use a high-quality interior latex paint in eggshell or matte finish. For the outside of the fireplace, a premium acrylic latex paint works well. Brands like Benjamin Moore Aura, Sherwin-Williams Emerald, and Behr Premium Plus all perform well on primed masonry.
What is the best color to paint a brick fireplace?
White, off-white, and light gray are the most popular. They brighten the room and work with almost any style. Charcoal and navy are rising options for a more modern look.
How long does a painted brick fireplace last?
With proper prep and a quality primer and paint, a painted brick fireplace can last 5–10 years before needing a refresh. Prep work is the biggest factor.
Can you use Sherwin-Williams fireplace paint on brick?
Yes. Sherwin-Williams Concrete & Masonry Primer paired with their interior latex topcoats works well on exterior brick fireplace surfaces. For inside the firebox, use their High Heat products instead.
How do you make a brick fireplace look modern?
Paint it a solid color, update the mantle, and keep the decor simple. A white or charcoal painted brick fireplace with a clean wood or marble mantel looks current without a full renovation.
Is painting over a brick fireplace permanent?
Mostly yes. Removing paint from brick is possible but very labor-intensive, requiring chemical strippers and significant scrubbing. Go in knowing it’s a long-term commitment.
What’s the difference between whitewash and paint on brick?
Paint covers brick fully and creates a solid color. Whitewash is a diluted paint mixture that lets some of the natural brick texture and color show through. Whitewash is easier to partially reverse and gives a more rustic look.
